Vertical shaft type eccentricity plasticity fan of windmill structure and auto speed change method by veritical shaft for action

摘要

The present invention relates to a vertical axial eccentric variable windmill structure for driving a power generation device and an automatic shifting method of a vertical drive shaft, wherein the eccentric which continues the inversion of the shock absorber 8 to the return point at the end of the moment supporting member 3 is carried out. A variable blade (A '; B'; C '; D') is installed to form a structure for operating the vertical drive shaft (2), the vertical drive shaft (2) by the power generation device by the RPM sensor for detecting the number of revolutions By forming the automatic transmission in (1) in a controlled manner, the eccentric variable gains (A '; B'; C '; D') of this windmill always generate strong driving force due to the change in the wind direction and the wind speed. Of course, as in the conventional fixed wing windmills, the rotational resistance of the wing hardly occurs on the reverse side of the wind direction, but rather the eccentric variable wing on the side of the reverse side causes a greater moment of rotational force than the case of the forward side, in particular depending on the wind speed. Windmills by letting the generator shift automatically When the driving efficiency is improved typhoon blows, the present invention relates to structure and how the automatic transmission of the vertical drive shaft of a vertical axis windmill to be poor seam variable wing is realized in which the no-load rotation of the windmill prevent the damage of the windmill.
